Connecting structure of umbrella tips

ABSTRACT

This invention discloses a connecting structure of an umbrella tip, which has an axial hole for receiving a tail rib. The tip has provided with a side engaging groove and the tail rib has provided with an elastic outward extended folded slice at its end side. While the tail rib inserts into the axial hole of the tip, the folded slice being firmly engaged with the engaging groove automatically. The manufacturing and the assembling of the tip and the tail rib are easy and convenient that obtains improved effect.

[0001] In order to connect with the periphery of the umbrella cover, itis always to connect with a tip at the end of the tail rib. The tip isprovided with a hole to connect with the cover being placed firmly onthe umbrella frame. A prior tip is shown in FIGS. 1 and 2, which has anaxial hole (11) and a said connecting hole (12). The tail rib (2) hasits outer end to insert into the axial hole (11) and a rivet (13) isused to combine the rib (2) and the tip (2) in secure. The manufacturingand assembling process is complex and uneconomic. Another known tip (2)is shown as in FIG. 3 and 4, the tail rib (2) has provided with a groove(21) at its end side and the tip (1) has provided with an elastic slice(14) having an inner hook (141) at a related position. When the tail rib(2) inserts into the axial hole (11) of the tip (1), the groove (21)will be engaged with the hook (141) of the slice (14) that obtains afirm engagement. It may ease the connection between the tail rib (2) andthe tip (1) but the manufacturing of the slice (14) will be moredifficult and trouble. And the plastic the hook (141) of the slice (14)may easily be broken under a pulling force in accident and the tip (1)may be also released from the tail rib (2) that causes the umbrella cannot be used in normal.

[0002] The primary object of the invention is to provide an inventedconnecting structure of an umbrella tip being different from any priorone and having better connecting effect. Now the features and advantagesof the invention will be described in detail with reference to theaccompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Please refer to FIGS. 5 and 6, the invention relates to theconnecting structure of the tip (1) and the tail rib (2), wherein thetip (1) has an axial hole (11) and a side engaging groove (15). The tailrib (2) has provided with an outward extended folded slice (22) at itsend side. Since the tip (1) is made of plastic or wood, the engaginggroove (15) can be easily formed. The tail rib (2) is made of metal andcan be pressed with the elastic folded slice (22) before it is assembledwith the tip (1).

[0010] When assembling, the tail rib (2) inserts into the axial hole(11) of the tip (1) very easily while the folded slice (22) is slightlypressed. As the elastic folded slice (22) reaches the engaging groove(15), it is automatically recovery and engages with groove (15) insecure. The tip (1) is thus connected with the tail rib (2) in a perfectengagement. Accordingly, the connecting between the tail rib and the tipis very convenient and due to the support of the engagement is the metalfolded slice (22) extended from the rib (2), it can provide a betterstrength and prevent from damage, which overcomes the drawback of aprior art.

[0011] Therefore, the invention is a technical advance. Evidently itmeets the requirements of granting a patent. We hereby file anapplication for a patent grant.

What is claimed is:
 1. A connecting structure of an umbrella tip havingan axial hole for receiving a tail rib, and the characteristic is thatthe tip having a side engaging groove and the tail rib being providedwith an elastic outward extended folded slice at its end side, and whilethe tail rib inserts into the axial hole of the tip, the folded slicebeing firmly engaged with the engaging groove automatically.
